Experimental study on large amplitude vibrations of a circular cylindrical shell subjected to thermal gradients

In this paper, an experimental study on large amplitude vibrations of a thin-walled shell, subjected to thermal gradient across the thickness, is presented. The temperature gradient effects on the shell dynamic behavior are investigated. The vibration tests are performed on a polymeric cylindrical shell that carries a top mass. The structure is harmonically excited in the longitudinal direction by means of an electrodynamic shaker. The results of the experimental study are here reported and discussed.
